SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, provide a full liquid formula oil-gas separation device for refrigerating system, the technical scheme of its adoption as follows:
an oil-gas separation device for a flooded refrigeration system comprises an oil inlet pipe, an oil-gas separation cavity and an oil-gas separation pipe, wherein the oil inlet pipe is communicated with the oil-gas separation cavity, the oil-gas separation pipe is a U-shaped pipe, an air inlet of the oil-gas separation pipe is arranged in the oil-gas separation cavity and is communicated with the oil-gas separation cavity, and an air outlet of the oil-gas separation pipe is arranged outside the oil-gas separation cavity; the bending part of the oil-gas separation pipe is arranged on the lower portion of the oil-gas separation cavity, and an oil inlet hole is formed in the side face of the bending part.
On the basis of the scheme, the number of the oil inlet holes is multiple, and the oil inlet holes are arranged on two opposite sides of the oil-gas separation pipe at the same horizontal height.
Preferably, the height of the air inlet is higher than that of the oil inlet pipe.
On the basis of the scheme, the distance between the air inlet and the inner wall of the oil-gas separation cavity above the air inlet is 1/4 of the diameter length of the oil-gas separation cavity.
The beneficial effects of the utility model are that: through seting up the inlet port in oil-gas separation pipe side, make fluid accumulate the take place oil-gas separation pipe after the take the altitude to along with letting in the gas of oil-gas separation pipe together discharge, effectively prevent fluid seepage once more in the oil-gas separation pipe, guarantee that the lubricating oil of accumulation can last a small amount of compressors, guarantee refrigerating system's stable high-efficient operation, and simultaneously, lubricating oil gets into and has reduced the cross sectional area of intraductal gas flow behind the oil-gas separation pipe, improves gaseous flow efficiency.
